Abstract
Objective Primary urethral carcinoma (PUC) is a rare malignant carcinoma but with limited therapeutic options. This review aims to provide an overview of the current strategies on this patient settings. Methods Recent literature ranging from January 1987 and December 2021 was assessed through PubMed search to assess the diagnostic and therapeutic principles of PUC. Results A complete of examination including cystoscopy, imaging, and biopsy should be conducted for these patients. Once diagnosed, the clinical decision of PUC should be made according to the tumor location, pathological pattern, and extent of the tumor. For patients with superficial and distal urethral lesions, organ sparing approaches or radical reconstructive procedures can be utilized. While for more advanced disease or nodal involvement, an optimal multimodal treatment strategy consisted of surgery and radiochemotherapy should be adopted. For patients with urothelial carcinoma of the prostate, the management including transurethral resection of the prostate followed by bacille Calmette-Guerin or radical cystoprostatectomy should depend on the infiltration depth of PUC. Conclusion A complete of examination is important for the diagnosis of PUC. The management of PUC should be determined by the location, pathological pattern, and extent of the tumor. More multi-institutional collaborations should be held to investigate better treatment modalities for PUC.

Abstract
The bulbar urethra is the most common site of anterior urethral strictures. In this case report, we present a 30-year-old male who was referred to us as a case of mid-bulbar urethral stricture. Urethroplasty was booked and a papillary lesion was found on routine diagnostic cystoscopy. An open biopsy was taken which showed invasive high-grade papillary urothelial carcinoma with squamous differentiation. This case is rare in terms of a young age of incidence, a lack of risk factors, an absence of suspicious symptoms, and a short duration of signs and symptoms. Urologists should consider workup for malignancy even in young patients who present with an idiopathic urethral stricture and a short duration of symptoms.

Triangular extension of hinge flaps: A novel technique to resolve stomal stenosis and prevent restenosis in staged buccal mucosal urethroplasty. Int J Urol 2021; 28:806-811.

Abstract
OBJECTIVES To verify the utility of triangular extension of a hinge flap in buccal mucosal staged urethroplasty to resolve stomal stenosis after the first stage and ultimately prevent restenosis. METHODS A total of 23 patients (triangular extension group) were studied in 2013-2019. In the first stage, buccal mucosa was transplanted, and an extended triangle portion of the mucosa was placed beside the proximal and/or distal stoma that was created when the stricture segment of the urethra was resected. In the second stage, during tubularization of the urethral plate, an incision was made at the stoma to increase the caliber to which the triangular extension was inserted. The procedure was considered successful when a 17-Fr flexible cystoscope passed through the reconstructed urethra at 6 months after the second-stage urethroplasty and no additional surgery or bougie dilation required. The clinical course of the triangular extension group was compared with 24 patients who underwent conventional staged urethroplasty (control group). RESULTS In total, 20 patients from each group underwent second-stage surgery. No patients in the triangular extension group required additional revision surgery because of stomal stenosis after first-stage surgery, whereas five (20%) control patients did. Urethroplasty was successful in 19 patients (95%) in the triangular extension group and in 19 patients (95%) in the control group. Uroflowmetry after the second-stage surgery indicated that the mean maximum urinary flow rate was 21.5 and 15.8 mL/s after triangular extension and the control procedure, respectively (P = 0.027). CONCLUSIONS The triangular extension technique reduces the need for revision surgery and prevents postoperative restenosis.

Abstract
Penile squamous cell carcinoma (PSCC) is a rare cancer with orphan disease designation and a prevalence of 0.1-1 per 100,000 men in high-income countries, but it constitutes up to 10% of malignancies in men in some African, Asian and South American regions. Risk factors for PSCC include the absence of childhood circumcision, phimosis, chronic inflammation, poor penile hygiene, smoking, immunosuppression and infection with human papillomavirus (HPV). Several different subtypes of HPV-related and non-HPV-related penile cancers have been described, which also have different prognostic profiles. Localized disease can be effectively managed by topical therapy, surgery or radiotherapy. As PSCC is characterized by early lymphatic spread and imaging is inadequate for the detection of micrometastatic disease, correct and upfront surgical staging of the inguinal lymph nodes is crucial in disease management. Advanced stages of disease require multimodal management. Optimal sequencing of treatments and patient selection are still being investigated. Cisplatin-based chemotherapy regimens are the mainstay of systemic therapy for advanced PSCC, but they have poor and non-durable responses and high rates of toxic effects, indicating a need for the development of more effective and less toxic therapeutic options. Localized and advanced penile cancers and their treatment have profound physical and psychosexual effects on the quality of life of patients and survivors by altering sexual and urinary function and causing lymphoedema.
